摘要： An improved aqueous electroless nickel plating bath and process for chemically depositing nickel on a substrate comprising an aqueous solution containing nickel ions, hypophosphite ions, a complexing agent, preferably a buffering agent and a wetting agent, and a small but effective amount of a sulfonium betaine compound sufficient to control the rate of nickel deposition and the concentration of phosphorus in the nickel deposit, preferably, in further combination with supplemental organic and/or inorganic rate stabilizers. The invention further contemplates a process for rejuvenating an electroless nickel bath which has been rendered inoperative due to the presence of excessive concentrations of supplemental stabilizing agents by the addition of a controlled effective amount of a sulfonium betaine compound sufficient to restore the bath to an operative plating condition.
